I've been wearing my hair in a balayage/dipdyed style for around 9 months now and I think it is becoming my signature. Although it seems like I use too many products for my hair, my balayage style is actually less maintenance than my once full head of blonde hair.
Being Asian, I'm prone to thick hair (and lots of it) and when we fry the ends to make them super blonde like mine, I suffer from dry hair and split ends.

To maintain, tone my blonde ends and to keep them smooth I follow this regime:

Styling and Treatment after Shampoo and Conditioning (Items 4,5,6):
While my hair is drying, I add Goldwell Stylesign Hot Form (Straight) (4) to my hair. This prepares my hair for the hair dryer and my straightening iron and it has a lovely fragrance. After I dry and straighten my hair, I add Goldwell Colorglow IQ Leave in Conditioner (5) to my ends. This is optional but I like to use it keep my ends smooth.
Then I apply KMS Polishing Serum (7) to smooth out my fly away hairs, this is also optional, my hair is not very tamed.

In Between Washes (Optional, Items 7,8):
I shampoo my hair every 3 days because my hair is very dry so it doesn't produce alot of oil over time; and I don't want to stress my hair by over washing. There are times though when my bangs/fringe will become oily so because its my focal point, I spray KMS Spray Makeover (hair shampoo) (7) in between washes to keep it refreshed.
When my hair becomes unruly and tangles, I sometimes use Shiseido L HPT (8) on my ends. I swear its a Miracle Worker, it really really does make my hair smooth and bearable to brush out my knots. I wouldn't be able to live without it. It's my secret weapon. And it's also optional.

Well there you are, that is my hair regime. Many of my lovely readers ask me how I maintain my hair. The photos above are just a collection of my hair over time. You can see the rosewood tones in my blonde ends from the De Lorenzo Rosewood shampoo and how the KMS serum keeps my hair smooth and polished all the time. Note, Photos 1,3, 7 & 8 are the result of getting my hair redone professionally at the hairdressers. You can see a beautiful tone and difference in the balayage gradient.

Your hair looks so beautiful! I love the ombre hair but I'm too scared to dye it myself ha! I got these instead - I&K dip dye hair extensions They’re available at Hairtrade.com and there's some gorgeous colours. I got the dark to blonde one and they look fab! Kate x
